Diced onions manufactured by Gills Onions and sold under the Trader Joe's label -- among others -- are being recalled because they may contain listeria, the Food and Drug Administration announced today.

Gills, based in Oxnard, Calif., said its pulling packages of diced yellow onions sold to retail and food service outlets in Oregon, Washington, California, Nevada, Arizona and New Mexico.

The recalled Trader Joe's diced onions were packaged in a 10-oz. bag with "Lot 2017-R" and "best if used by date of 06/16/07" printed on the package. Other packages were in 4/5-pound cartons and labeled under the Gills Onions and Sysco Natural brands, both with "Lot 2017-R"and a "best-if-used by date of 06/16/07" on the front.

The recall was announced after Washington state's Department of Agriculture detected listeria monocytogenes in one of the Trader Joe's bags.

Listeria monocytogenes can cause serious and sometimes fatal infections in young children, frail or elderly people and those with weakened immune systems. The organism can cause short-term symptoms such as high fever, severe headache, stiffness, nausea, abdominal pain and diarrhea in healthy people. Listeria infection can cause miscarriages and stillbirths among pregnant women.

No illnesses have been reported in connection with this product.
